Candida auris is a fungal pathogen that has recently emerged as a global threat to public health. It was first described in Japan in 2009 and has since been reported in 17 countries on five continents. This case report describes the first reported case of multidrug-resistant C. auris in Canada. In May 2017, a 64-year-old individual was evaluated for chronic otitis externa. Past medical history included a recent hospitalization in India for elective oral surgery that was complicated by an odontogenic brain abscess. Upon return to Canada, the individual was admitted to a hospital for neurosurgical drainage of the brain abscess and parenteral antibiotics. Early during hospitalization, the patient was identified as a carrier of carbapenem-resistant Enterobacteriaceae and was placed on contact precautions. Also early during this hospitalization, a chronic otitis media was managed with placement of a typanostomy tube with drainage of clear fluid from the ear, which continued through the admission and after discharge to a post-neurosurgical rehabilitation facility. During outpatient follow-up, swabs of the ear discharge cultured C. auris that was resistant to fluconazole and amphotericin B. There was no clinical response to ototopical antifungal therapy. Surgical evaluation for management of the otomastoiditis is pending. There is a potential for C. auris to cause infection in health care settings. It can persist in hospital environments, has the potential for transmission and can cause invasive disease. It is difficult to identify and is often resistant to antifungal medications. The application of infection prevention and control recommendations can help prevent nosocomial transmission. It is now prudent to consider the risk of C. auris, in addition to the known risk of other antimicrobial resistant organisms, in any traveller who has been hospitalized while outside the country. When identified, contacting local public health can assist in the tracking and management of this emerging disease.
